Low-pressure-induced large barocaloric effect in MnAs0.94Sb0.06 alloy around room temperature
压热制冷由于其环保以及高效等优点被认为是很有可能替代传统气体压缩制冷的制冷方式。然而，目前所发现的大部分压热制冷材料的驱动压力都很大，不利于实际应用。在这篇文章中，我们报道了一级磁结构相变合金MnAs0.94Sb0.06在低压力下诱导的压热效应。MnAs0.94Sb0.06合金的相变温度对压力非常敏感，其压力系数dTc/dP在降温时为134 K·GPa-1，在升温时为126 K·GPa-1。在40 MPa的微小压力下，M...
